Patent SE-8400885-D0 (SE)
Inventor: WANTKE J
IPC: G01R31/34
Filed: 1984-02-17
Abstract: The invention relates to a device for detecting shorted turns in rotors of collector machines. In spite of careful fabrication, there is always a risk that shorted turns occur in the rotor. It is therefore the object of the invention to create a protection for the motor mentioned initially, which detects the shorted turns in the rotor during operation and switches off the motor as quickly as possible. The device according to the invention for detecting shorted turns in rotors of collector machines is characterised by the fact that a sensing probe arranged close to the collector is provided in the machine housing, which probe detects the variable magnetic fields of the rotor, occurring in the individual windings due to the short- circuit current in the event of shorted turns, during its rotation. This invention makes it possible for the first time immediately to detect shorted turns in the rotor so that no greater damage occurs in the rotor. Shorted turns generate a short-circuit within the rotor winding so that, in addition to the normal current, the short-circuit current also flows through one or several turns.

Abstract: A drill chuck usable in a drilling device capable of rotary or rotary-percussion drilling, includes radially adjustable clamping jaws with the clamping surfaces of the jaws directed inwardly towards the central axis of the chuck. Each clamping jaw has at least one projection extending radially inwardly from the clamping surface for engagement in correspondingly shaped recesses in the shank of a drilling tool insertable into the chuck. The clamping surfaces form guide surfaces for the drilling tool so that the drilling tool is adequately guided over large surfaces extending in the axial and circumferential directions in the chuck.

Abstract: A self-contained portable ventilator/resuscitator which can be operated from either an internal power source, or in the event that the power source fails, can be manually operated to provide the patient with a supply of filtered ambient gases. The ventilator/resuscitator includes a housing (12) in which is mounted a chlorate candle (36), a filter (38), a pump (32), and control means (34). The pump is caused to be operated by the chlorate candle and will cause ambient gases to be drawn into the filter to be mixed with the output of the candle for subsequent delivery to the patient. The device further includes an accumulator (14) which, during normal operation, stores excess gases during the expiratory cycle, and, in the event that the chlorate candle ceases operation, can be manually operated through movement of the handle (90) to either draw gases into the accumulator through filter (38) or to force the filtered gases into the lungs of the patient.

Abstract: A bacteriophage is added in order to combat the formation of sediment and slime caused by bacteria, which in turn detracts from the quality of the paper or cardboard being produced, and involves the addition of a phage of tailed A or B series of the particular bacterium isolated. Once the correct bacteriophage has been determined, and most frequency this is related to the bacterium Klebsiella pneumoniae, it is added to the process water where it infects its hot bacterium, which commences to multiply it. When a suitable number of phages have been produced within a bacterium cell, the cell wall splits with the aid of lysozyme enzymes. This leads to the host bacterium being destroyed, and new phages are liberated to infect in turn fresh host bacteria in a limited chain reaction.

Abstract: The vehicle fuel tank has a filler pipe and cap, and its exhaust gas system (3) incorporates a catalyst. A connection is provided between the tank's normal highest level, i.e. that of the filling pipe, and the exhaust gas system between the connections of the latter to the engine and to the catalytic exhaust gas cleaner. - Via the connection, the fumes liberated during the tank filling process are evacuated via the vehicle ordinary exhaust system. The connection may need to be provided with some form of air pump. When the fumes pass through the catalyst, a redn. occurs, and a large part of the hydrocarbon content is reduced to carbon dioxide and water. A connection may be provided between the tank and the engine fuel system ahead of the engine so as to eliminate fuel fumes when the engine is running during the filling process.

Abstract: Harmonization process for a day/night missile firing system in which the day channel includes a day telescope (1) (3), a laser beam guidance transmitter (7) (9), and a collimator/deviation measurer (10) (12) and (13) and the night channel includes a heat camera (17) (18). The harmonization of the guidance transmitter is carried out permanently by returning part of its emitted flux into a deviation-measuring receiver (14) by means of separators (16) (15) and (13). The harmonization of the heat camera is similarly obtained permanently by means of the invariant trihedron subassembly (19) (20) which returns the infra-red flux in the focal plane (18) of the camera. The infra-red image of the reticle of the collimator is thus superimposed on the image of the reticle of the terrain. The eyepiece of the day telescope is used for the observation. The IR reticle is projected in the heat camera at a wavelength shorter than the main operating band. <IMAGE>

Abstract: For establishing two-way communication links between processes in a distributed operating system, the processes are provided with ports through which communication between the processes is performed. The processes and the ports make possible for the operating system to keep a check on processes having links and to use these links also if the process per se is terminated, and to discover an error in the process and terminate it. For enabling the operating system to be able to transmit via the links information regarding process or computer drop out and thus be able to propagate this information through the whole chain of linked processes, and to report this information to applications executed in the linked processes in order to enable these to undertake application specific measures, a code is used which is called at link abortion and communication errors. The function of this code includes terminating an erroneous process and reporting the error to an error handling code. The first mentioned code is always executing in a process to which an error has been reported.
